This invention relates to jacks for shoe machines and particularly to jacks for use in connection with lasting machines.

The invention is herein shown as embodied in a jack adapted especially for use in connection with the type of machine known as the Hand Method Lasting Machine, an example of which is shown in my pending application Serial No. 127,116, filed October 18, 1902, of which this application is a division and which matured into U. S. Letters Patent No. 1,081,872 on Dec. 16, 1913. I

The object of the invention is to provide an improved shoe-supporting jack by the use of which shoes can be lasted much better and with less labor than has heretofore been possible. It has become the custom to use in many grades of shoes straight counters or heel stiffeners, that is, counters which are provided with straight flange portions in stead of counters which are provided with molded flanges, and to last the shoe by bend ing or breaking the flange portion down upon the innersole in the same operation in which the upper material is laid over the innersole. The advantage of thus breaking down the flange of each counter during the lasting operation is that the counter is thereby conformed to the particular last on which the shoe is being made, and a better fit of the shoe is obtained. 7

An important feature of my improved shoe-supporting jack consists in means by which the counter portion of the shoe is caused to conform accurately to the corresponding portion of the last. A difliculty which develops in breaking down the counter flanges of shoes by machines as heretofore constructed is that when the flange is bent and broken over upon the innersole the body-portion of the counter is sprung away,

from the counter portion of the last, and the shoe is thereby caused to bulge outwardly at this point, instead of conforming to the shape of the counter portion of the last, as it should do. To remedy thisv difliculty the jack of the present invention is arranged to clamp the shoe between toe and heel embracing bands, and the heel-band is so constructed that it will conform to the shape of the counter portion of the last, so that when the shoe is inserted in the jack and the heel-band is brought into position about the heel portion ofthe shoe, the counter is securely clamped between the band and the last and cannot spring away from the last during the breaking-down operation. The heel-band is also supported on peculiarly shaped spring arms which cause said band to embrace and clamp the sides of the heel end of the shoe and force the shoe to conform accurately to the shape of the last at the end portions of the counter.

Another feature of'the new jack consists in means for preventing the formation of wrinkles in the toe portion of the shoe by the upper manipulating devices during the lasting operation. It has been found very difficult in lasting shoes made of certain kinds of leather to avoid forming fine wrinkles in the leather while stretching it with the grippers, particularly at the toe portion of the shoe. To overcome this the jack of the present invention is provided with means for wiping and stretching the upper over the whole of the toe portion of the last at the same time, and then clamping and holding the upper around said toe portion of the last until it is secured in position by the lasting and securing devices. The jack has a last-pin so mounted as to permit the last to be tipped slightly in a longitudinal direction toward the heel, and thereafter the last, coming into contact with the heel-band, is held against further longitudinal movement, and because of the binding of the last against the last-pin and the clamping of the shoe by the heel-band the last is also held against upward movement during the wiping and stretching of the upper over the toe portion of the last. The means herein shown for thus wiping and stretching the upper over the toe portion of. the last is a toe-band which is arranged and actuated to first with the upper on the underside of the -toe portion of thein verted last and to tip the last upwardly. and backwardly vwithin the heel-band. In so doing the toe-band Wipes up along the toe portion of the shoe and over the toe end of; the last so as to stretch the upper, and thenv embraces the toe portion of the upper thus stretched around the toe of the last and holds such portion of the upper clamped in this position, -The toe-band thus acts to last partially the toe portion of the shoe as it wi es the upper over the last, and there'- While the movement of the toeband up- Wardly along the forwardly inclined face of the toe end of a'shoe will "of course force the shoe rearwardly toward and into the heel-band, this result is greatly facilitated by actuating thetoe-band rearwardl'yas well as upwardly while it is in engagement with i the toe end of the shoe, and to this end a further feature of my invention consists in imparting to the toe-band during its movement into clamping engagement with the toe end of the shoe a movement rearwardlyor toward the heel-band for forcing the shoe firmly into the 'heel-band. As herein shown, this is effected by 'so'connectin-g the toe-band to the toe-rest that after said band and rest both come into firm engagement with the shoe the toe-rest will act as a fulcrum about which the toe-band will turn upwardly and rearwardly for forcing the shoe toward the heel-band a tthe same time that the upper is wiped toward the bottom of the last. the construction shown the toe-rest and toeband are'attached to a rigid'carrier which is pivotally'connected to an actuator "shown as a post arranged for longitudinal movement only. The plv'otal connection permits the carrier to rock upon the post until the'rest and band "have each become seated against the shoe and the shoe-hasinoved rearwardlyi into the heel-band. The' resistance which the yielding support for the heel-band offers to a further rearward movement of the shoe then checks the free tipping movement of the shoe, and in the further rise of the post the toe'srest becomes a fulcrum about which the carrier and toe-band turn as the hand rocks upwardly and rearwardly for effect-1 ing the doubl'e purpose of wiping'the upper toward the last bottomand fo'rcingthe shoe backwardly into the heel -'band.- The toe band and the heel band may be considered tobe lasting devices because'they perform l'ast-' ing functions in shaping the shoe stock'to the last as will herein mo-refullyappear.

These lasting means for the opposite ends of the shoe are mounted to permit a relative movement between them for adaptation to right and left crooked lasts. The advan tagesof this mounting will be readily apparent. .Themovement is curvilinear about an axis which is located under the last between the toe and vheel bands and at a substantial distance from the ends o f' the last. In the illustrated embodiment of the invention the toe band is the movable lasting means, its carriage being mounted to turn about a vertical axis in the longitudinally movable toe post before mentioned as supportii'ig thecarriage. The pivotal connection between the band carriageand the post is here shown as located at substantially the center of the toe band which is equivalent to the approximate center of curvature of-the toe end of the last.

The invention is'notf limited to "the exact location. Preferably the I toe-rest is pivotally connected tojits carrier so that it may rock to seat itselfsquarely upon the portion of shoe engaged by it and so that in the rearward movement of the shoe it may move with the shoe, thus avoiding the friction which might otherwise be produced by the shoe sliding over the rest.

' Another feature'of my improved jack consists in mounting the last-pin so that it may tiptransversely of the length of the. jack. In some lasts the holes for the last-pin are inclined laterally and when the last is supported on afvertical pin ofa jack, one side of the last bottom ishigher than the other side. For the purpose of adapting the jack to support such lasts in proper position, I have movably mounted the last-pinso that it may accommodate itself automatically to the inclination of the hole made for it inthe last. For the best'results in overcoming the above-mentioned difficulty the last-pin should be capable of tipping about a center which is at or near its upper end and I have therefore mounted the pin in'a carrier adapted to slide in suitable gu'ideways to give the pin the desired movement.

ice

Another feature of the invention consists in means for adjusting the toe-band to adapt it to fit lasts which are so shaped that the bottom of the forepart is higher on one side than on the other. It is found that some lasts are so formed that the plane in which the bottom of the forepart lies is not parallel with the plane in which the bottom of the v heellies, but is inclined thereto in a direction transverse of'the last; in other words,

the last is twisted. When such a last is positioned properly in the jack with theheelbandflush with theinnersole upon the last at both sides, the forepart of the last on one side extends above or below the planein which the top "of the toe-band is positioned, and the shoe therefore cannot be'presented properly to the lasting machine. To overcome this difliculty I have provided means for adjusting the toe-band to cause it to conform to the shape of such lasts. In the construction herein shown, this object is accomplished by movably connecting one end of the toe-band to its support, whereby that end of the toe-band can be raised above or depressed below the normal plane in which the top of the toe-band lies to position the toeband so that its top edge will be parallel or flush with the bottom of the last all the way around the toe of the last when the toe-band is moved into operative position for embracing the toe of the last. These features of my invention and others, including certain com binations of mechanisms and details of construction, will be set forth in detail in the following specification and pointed out in the claims.

Figure 1 is a side elevation of a jack embodying the invention, a shoe being shown in the jack and presented thereby in position to be operated upon by a lasting machine. Fig. 2 is a side elevation of the jack partly in section and shows the relative positions occupied by a shoe and the several parts of the jack prior to the actuation of said parts for jacking the shoe. Fig. 3 is a similar view showing the relative positions of the several parts when the shoe has been jacked. Fig. 4 is a plan view of the jack and shows in outline the position of the toeband and heel-band when a right shoe is clamped in the jack. Fig. 5 is a perspective view of the last-pin and its supporting means. Fig. 6 is an enlarged detail of a section on line 6-6 of Fig. 1. Fig. 7 is a vertical longitudinal sectional view through parts shown in Fig. 1. Fig. 8 is a detail showing contrasting positions, and Fig. 9 is a transverse sectional detail.

The jack comprises a base plate 1 upon which is guided the carriage 2 for supporting the toe-rest 4t and toe-band 6 and the carriage 8 for sustaining the last-pin 10 and the heel or counter-embracing band 12. The

carriages are adjustable toward and from each other for shortening or lengthening the jack by a right and left threaded screw 14; which is secured against longitudinal movement in the base plate and is provided with an operating crank 16.

The heel carriage 8 has cars 18 between which is pivoted a support 20 for the lastpin 10. The lower face of the support is formed, as shown in Figs. 2 and 5, to have limited rocking movement about its pivot and the spring plunger 24.- is arranged in a socket at the rear of the pivot to rest on the carriage and hold the support and last-pin normally tipped forward. This positions the last-pin sufliciently away from the heel-v band, as shown in Fig. 2, to enable the last to be readily placedupon the last-pin and pin.

permits the pin to be rocked backwardly when the last is forced into the heel-band during the operation of jacking the shoe. The support 20 is shaped, as shown in Fig. 5, toprovide two curved guideways 26 and 27 adapted to receive respectively a rib 28 and the end portion 29 of a block 30, which is formed with a socket in which the last-pin is yieldingly' upheld by a spring 32. The guideways 26 and 27 are concentric, being formed upon curves which have their center at a point near the upper end of the last- This construction enables the last-pin to rock transversely of the jack to compensate'for any inaccuracy in the direction of the pin hole in the last. The carriage 8 is provided on either side with ears 34 to which are pivotally connected the opposite ends of a U-shaped casting 36. The casting has upwardly extending arms 38 and to these are rigidly secured springs 410 which are curved and twisted, as shown in side and end elevations in Figs. 3 and 4. The heel-band 12 is pivotally connected at its ends to the upper ends of the springs 40 and to the rear portion of the heel-band is secured the upper end of a resilient brace 42 extending downwardly to the carriage. The casting is adapted to be adjusted about its pivotal connection with the ears 34 for moving the heel-band forwardly or backwardly with relation to the last-pin by means of the screw 14 carried by the casting and adapted to bear upon the carriage.

As herein shown, the heel-band comprises an outer layer or strap a of strong, tough leather, an inner layer Z) of hard, firm, wear-resisting leather, and an intermediate piece 0 formed wedge-shape in cross-section and serving to shape the band so that it conforms to the vertical curvature of the heel portion of the shoe. Between the inner and outer layers and fitting closely against the upper portion of the inner layer is a strip cl of spring metal which serves to support and give rigidity to the inner layer of hard leather and to give resiliency to the heelband as a whole. The outer layer 64 gives the band the requisite strength and 11X1- bars 15, is pivotally connected as herein" shown to the heel-band supports 40, the outer ends of the bars being joined by a cross-piece which constitutes a handle. A yoke-shaped member 16 is connected at its ends to the lever and is adapted to extend over the heel of the shoe which has been applied to the last-pin ready to be jacked. The upper end of the yoke is provided with an adjustable contact member 17 for engaging the heel portion of the innersole of the shoe whenthe yoke is in its operative position. The pivotal connections between the yoke and the lever are so located that when the lever is depressed from the position shown in Fig. 2 toward the full line posi tion shown in Fig. 3 the shoe will be drawn downwardly against the pressure of the spring sustaining the lastpin and also somewhat backwardly into the heel-band until its upper surface is. flush with the upper edge of the band. The location of said pivotal connection with relation to the fulcrum of the lever on the supports etO is such that the yoke is fully depressed when thelever is in approximately its lowest positionyshow n in full lines in Fig. 3, and the weight of the lever and'the friction of the parts will then hold the shoe in this position until it is clamped between the heel-band and the toe-v band'. It is to be noted thatthis construction comprising the yieldingly supported last-pin and the depressing means'constitutes a convenient arrangement by which lasts differing in thickness may be posis tioned at the proper altitude with relation to the "heel-band and will beheld in such 'positionwhile the operation jacking the shoe is carried out. I

The carriage 2 at the front of the jack is provided with a guideway extending upwardly and forwardly to receive a post 50.

A carrier 52 is connected by vertical and horizontal pivots to the upper endof the post, the vertical pivot being. advantageously located substantially at the center of curvature of the toe portion of the last when a shoe is in the jack, as at 51 in Figs. 9 and i, and comprises a rearwardly extending arm 5t and depending outwardly inclined arms 56. The toe-rest 4 is pivotallysupported upon the arm 54 and is provided with a depending finger 58 which is engaged by a,

spring 60 secured to thecarrier. The spring 60 holds the rest normally in its most advanced position, but perm-its itto rockirearwardly during the operation of jacking the shoe, as will be described. To the dependband.

end. As herein shown, (Fig. (3) this adjustable connection comprises an eccentric bushing 64 mounted on a pivot stud 66 and received in a circular aperture in theupper end of the arm 68 of the holder.

which it may be turned for'raising or lowering the adjustableend of the toe-band with; The toe-band may f thus be adjusted to position its opposite side portions at different levels to locate its edges relation to the holder.

The eccentric bushing has a finger piece by means of.

flush with the adjacent edges of the forepart. of a twisted last being j acke'd. The post 50 is arranged to be moved longitudinallyjin the carriage 2 for raising and lowering the toe-rest and toe-band,,and to this end the 4 post is provided, as shown, with rack teeth which are'e'ngaged by a pinion 70' carried by a shaft 72 which is mounted in a bearing 73 formed on theside of the carriage 2. -An

operating handle 74 is secured to the shaft 2- for turning the pinionand the handle is provided with a: pawl 7 6 adapted to engage with teeth. on a circular plate 78, secured to.

the carriage or the shaft bearing. The handle may be lockedby the pawl 7 6 for holding thetoe-b-and in its elevated position.

Thesidearms of the toe-band holder 62 are formed to hold the end portions of the'band separated adistance greater than t-he'width of the widest shoe which the jack is in tended to receive. When the toe-band is pressed against the toe of a lastthe front arm of the holder yields and the side arms are drawninwardly to force, the side .por-

tion's ofthe toe-band into clamping contact with the-sides of the shoe so that the whole of thetoe portion of the shoe is firmly ems bracedby t-he toe-band.

' The shoe is applied to the jack with the parts, excepting the yoke 46, in the position shown in Fig. 2, the'last-pin tipping transversely or longitudinally of the jack to adapt itself to any inclination of the pin hole, The yoke 46 is then swung from the dotted line position shown in Fig. 3 to the fullfline position-shown in Fig. 2, and the lever 45 is moved downwardly for forcing the shoe "bac'kwardly and downwardly with relation to the heel-band until the bottom of the shoe is flush with the top of the heelband. The operator thenobserves the shape of the last-, 'and i f it is a twisted last having one side of the forepart higher than the other side, he relatively adjusts the two sides of the toe band vertically by means of the eccentric 64L untilits edges on opposite j sides of the shoe lie in a transverse plane parallel with the bottom of the last and hence when the toe band-is turned into its operative position they will assume a position flush with the last on both sides. The handle 74 is now depressed for inoving the carrier52 with the toe-rest and toe-band in the direction of the length of the post- 50. The first effect produced by this movement is to force the shoe backwardly into the heelband, the last-pin tipping about its pivot in opposition tothe spring plunger 24: as the toe-rest and toe-band becomefirmly seated against the forepart of the shoe. 'As the band is closedby thisnioveinent about, the last below the fuller or wider portion of the shoe and the slope of the toe end face of the -'last it occupies a position with its acting edge, Fig. 2, substantially parallel with the plane of the last bottom and it maintains this relation to the plane of the last bottom while it is finally lifted to the position, Fig. 3, for wiping the upper toward lasted relation to the end and side faces of the last, The carrier 52 and the toe-band then rock about the toe-rest as a fulcrum and as this fulcrum is below the acting edge of the toeband said edge will travel upwardly and backwardly and force the shoe farther rearwardly into the heel-band at the same time that it wipes the upper toward the bottom of the last. In this final movement the resilient arms of the holder 62 for the toeband yield to permit the band to adapt itself to the increasing size of the fuller portion of the last over which it is raised and to the contour of the toe end of the last.

The movable connection between the toel'est and its support permits said rest. to move with the shoe in its backward movement, thus avoiding the friction which might otherwise be produced by the shoe being compelled to slide over the rest. The backward pressure of the shoe against the middle portion of the heelband causes the spring supporting arms 40 to yield, and because of the peculiar formation of these arms with an ini ial twist as shown in Fig. 4, they twist farther as they yield, their inner ends moving toward the last and causing the end portions of the heel-band or counter-embracing-band to clamp the sides of the shoe at about the ends of the counter, whereby the of the last.

end portions of the counter are held firmly against the last. When the heel portion of the shoe has been pressed firmly into the heel-band said band, cooperating with the last-pin, prevents the forepart of the shoe from being raised any higher and then the toe-band begins to ride up the toe portion of the shoe, the carrier 52 tipping about its pivotal connection with the post to permit the band to rise with relation to the rest. The resilient holder for the toe-band is so shaped that the sides of the band areheld separated far enough to receive the widest shoe for which the band is adapted, and therefore the shoe at first is engaged by the middle portion only of the band; but as the band is forced forwardly and upwardly along the toe portion of the shoe, the middle arm of the holder springs forwardly and the side arms are drawn inwardly to permit the band to adapt itself to the shape and size of the toe portion of the shoe. As the band continues to rise it therefore wipesthe whole toe portion of the upper toward the bottom of the last, thus precluding the forming of an fine wrinkles in the upper material, and. by the time the edge ofthe band reaches a position flush with the bottom of the last saidband has firmly clamped the upper material against the toe and sides t is to be noted that the toeband engages first by its middle portion with the upper on the toe portion of the last, as shown in Fig. 2, and that during the first part of the wiping movement of the band the upper is stretched in a direction longi- Thereafter as the band conforms to the shape of the toe portion of the last, the sides, as well as the middle portion, of the band comes into engagemei'it with the upper, and in the final rise of the band the upper on the sides of the last also is wiped toward the bottom of the last. When this movement has been completed the parts occupy the position shown in Fig.

3 with the resilient toe-band holder and the heel-band supporting springs under tension, the toe portion of the upper and also the counter being clamped firmly against the last so that the upper can not wrinkle at t toe or the counter spring away from the last at the frontvends of the counter or bulge outwardly from the heel of the last when the counter flange is broken down during the lasting operation. f The pawl carried by I the lever A will engage the ratchetteeth on the disk 7 8 and hold the parts of the jack in the positions to which they have been moved. The lever 45 may now 'be raised to release the yoke and said lever and-yoke moved into the relative positions shown in dotted lines in Fig. 3, and swung down-' wardly where they will be out of the way, The base 1 and the described parts carried by it are supported on a post 80, Figs. 1 and 7, to which the base is connected by a cupand-saucer joint, the cup-shaped lowerface S2 of the base inclosing a plate 83between which and the saucer-shaped head 8% of thepost clamping action, fixing thebase in angular relation to the post, is effected by a stem 85 and a lever 86. There is a relief spring. between the head of vthe stem and the plate 88. and the lever is fulcrumed on the post and is operated through a rod 87 from the driving mechanism of the machine, Figs. 1 and 7, of which the jack is herein shown to be a part.

The jack post 80 is sustained by a lever 90 with which it has a connection permitting tipping laterally and also forwardly and backwardly between shoe receiving position and the operative position in which the shoe on the jack is presented to theumachine.

The lever 90 isfulcrumed on the base of the machine at 92 and its rear arm contains asocket in which the lowerend of a strut 94; rests at a point near the fulcrum. The strut extends obliquely upwardly and rearwardly to a spring chamber in the machine frame, H

where it abuts against the thimble or cap 95 of; the counterbalancing spring 96, Figs. 7 and 8. The points of engagement of the strut with. the spring cap 95 and with the lever 90 are so related to the fulcrum point 92 of the lever that the strut makes an increasing angle with the direction in which the force I of the'spring is exerted as the j ackis depressed, see full lines Fig. 8, whereby the jack may be stable in its depressed position. As the jackis' raised the springs force is transmitted bythe strut with increasing directness and effectiveness, see dotted lines Fig, 8, so that the spring will hold the jack in itsjupraised position; Thus thestrut 'con stitutes a connection between the balancing spring 96 and the jack for causingthe said spring oractuator to act with lncreasmg force as the jack is moved to its operative position. A'screw 97 provides for adjusting the force of the sbring '96 to balance the weightofthe jack and different shoes.

a The jack "may be intermittently locked against angular movement on the head of its post 80 and unlocked automatically through the .rod 87 which is connected by a lever 100 and rod to a rack bar 102 that meshes with r a pinion 103, Fig. 7,: having connection through a ,lever lO and rod 105"with a swinging cam arm 106, Figs, '1 and 7,, that rocked the vibrating lever 108 the upper end of which bears a roll standing in a groove in av cam blockon the driving shaft of the well known lasting machine shown a in Fig; 1. As the lever 108 swings toward the left'it rides up and; engages the cam face on the swinging arm 106 and through the C pinion 103 draws thefrack bar 102 up,"thereby drawing down uponrod 87 and plate 83 to lock the jack. "During reverse moyement oflever 108" the rack bar is allowed to rise,"

as it does, under the action of a spring plun} ger 110 which sustains and presses upwardly against lever 104 From Fig.7 it may be seen that excess upward movement of'the rack bar 102 after the jack has beenlocked against angular movement upon the head of post 80 will bodily lift the lever 100 and, raisethe front end of lever'90 and the entire jack. The cam face on arm 106 is preferably so formed that such excess movementof the rack bar shall occur and that the jack shall be, so; raised unyieldagainst angular movement on the: post 80.
